What's really strange is that the NTLM authentication helper modules were built
for Squid, so one is lead to believe that NTLM authentication will work. This
is not the case. Squid must be built with the '--enable-auth="basic,ntlm"'
argument to configure in addition to the helper module flags in order for NTLM
support to be activated.
To fix this problem, the Red Hat release engineer need only add the above
configure flag and rebuild the package.
